2 Overview Introduction The new Autosorb 6iSA provides six ports for independent analysis of 1 to 6 samples. Dedicated pressure transducers, dewar flasks, coolant level sensors, and Po cells allow independent and simultaneous operation of each station. Its Windows -based software, available as a CFR-21 Part 11 version, provides the ability to perform a multitude of data analysis methods including single and multi-point BET Langmuir surface area, mesopore volume and size distribution, micropore area, total pore volume and much more. Modern data communication provides ease of data input and export. Features - Benefits Quantachrome s AUTOSORB 6iSA is designed to satisfy the needs of laboratories with high analytical throughput for rapid and accurate surface area and pore size data. Fully automated analysis of surface area, pore volume and pore size measurements. (continued) Low maintenance, vacuum volumetric system with stainless steel manifold construction. Speed and precision ensured by MAXIDOSE a proprietary dosing algorithm that responds and adjusts to the adsorption demand of the sample. High resolution adsorption and desorption isotherms defined with up to 180 equilibrium data points. Six analysis ports, each with its own dewar (coolant flask) and pressure sensor, provides independent and simultaneous analyses for the highest analytical throughput. Windows based software provides for instrument control and a comprehensive range of classical and modern models for reporting surface area and pore size. System supplied complete and ready for operation includes vacuum pump, dewar flasks and sample cells. Dedicated station pressure transducers ensure equilibration is monitored in smallest enclosed volume in addition to allowing simultaneous operation. Dedicated Po cells ensure accurate P/Po values. Fresh samples can be started while other analyses are already in process. 1

4 ASWin Software Windows -based Performance The Autosorb 6iSA analyzer is microprocessor controlled, and communicates with a Windows based PC utilizing Quantachrome s state-of-the-art, data acquisition and data reduction software. Comprehensive software to meet modern needs The Autosorb software is highly functional and user friendly. It function Incorporates an advanced database that allows users to quickly search accumulated data files by specific ID, description, operator, comment or range of dates. The Autosorb software is superior for data reduction, incorporating classical methods and the latest DFT (Density Functional Theory) and Monte Carlo models. The user-friendly software guides you through analysis setup, preprogrammed parameter recall or making settings for operations, data reduction, graphs and report printouts. Multiple graphs to view isotherm and related plots. Data Presentation A comprehensive range of surface area and pore size methods is available: Adsorption and desorption isotherms. Multi and single point BET surface area (including constant and correlation coefficient). Micropore BET assistant uses iso 9277:2010 method Analysis parameters in Autosorb software During operation one can view the accumulated data, the isotherm and all associated graphs and analytical results up to that point. After a run, reports and graphs can be archived across local network and/or printed automatically or the operator can use the software to determine the best fitting method, to compare data by overlaying curves or to adjust graph, size, scaling, titles, plot markers and line colors for best print out. 3 Langmuir surface area.

5 21 CFR Part 11 Software Includes many features that support these regulations and provide the necessary tools for customer compliance. ASWin-CFR Software Functions Relating to System Access, Electronic Signatures and Security. Required login with unique user i.d. / full name combination. Password aging and forced change. Automatic user account expiration and / or manual suspension. Selectable minimum i.d. and password length. Three user levels gives three privilege levels. Access level programmable by administrator level. Programmable session time-out (auto log-off through inactivity). Tamper resistant binary-encoded data files. Data security is established through the closed Autosorb / ASWin system. CFRb Software- Audit Trail. 21 CFR Part 11 The Autosorb 6iSA, when configured for security and used with its 21 CFR Part 11 version of ASWin software, is designed to allow the user to meet the regulatory requirements for electronic records within the pharmaceutical and allied industries as set forth by the US Food and Drug Administration (FDA). The FDA intends to enforce Part 11* compliance under FDA Regulations, the Federal Food, Drug, and Cosmetic Act and the Public Health Service Act as outlined in its 2003 Guidance for Industry Part 11, Electronic Records; Electronic Signatures Scope and Application prepared by the Office of Compliance in the Center for Drug Evaluation and Research (CDER). This version of the Autosorb 6iSA software adopts software design features to allow for easy integration into pharmaceutical and other GLP laboratories. * Final Rule, Federal Register / Vol. 62, No. 54, pp , 1997 Audit Trail Functions & Reporting Features Data reduction parameters (metadata) used to calculate final results are included as part of the data file. Operator user level does not have the access privileges to change meta-data. Changes to meta-data are reflected in the audit trail. Data files acquired by means other than directly from the Autosorb instrument are flagged as such in the audit trail. The audit trail does not obscure previous entries; old and new values are both recorded and visible. The audit trail itself cannot be edited and is included as part of the securely encoded data file it cannot become disconnected. Changes to meta-data require that the user enter a reason, to be in accordance with the underlying predicate record rules, which is then retained as part of the audit trail. The audit trail is included in all human readable formats, screen display, print preview, PDF and hard copy formats. Multiple page report sets are linked by a unique report i.d. generated automatically by ASWin. 4

6 Sample Preparation: Degassers Consistent and reliable surface area and pore size results depend upon proper sample preparation procedures. In terms of B.E.T. analysis, the limitation in throughput is often sample preparation. The complete degassing of samples can often require several hours, while surface area measurements may require as little as 30 minutes. Quantachrome manufactures several models of degassers to fulfill your sample preparation needs. These degassers provide a virtually continuous supply of properly prepared samples for the AUTOSORB 6iSA Surface Area and Pore Size Analyzer. XeriPrep Degasser The gold-standard in sample preparation for physisorption analyzers. It provides PC control of all heating zones with individual heating ramps and times. The Built-in cold trap enable efficient removal of condensables at low degassing temperatures and for a clean vacuum. Turbo- pumped version available for rapid high-vacuum degassing. Vacuum pump included. MasterPrep Degasser Fully featured preparation unit. Individually heated stations with programmable heating profiles for R&D, commercial labs and multi-user laboratories. Dual modes (vacuum or flow) for further flexibility and optimization. Temperature control and logging via PC software (included). Integral cooling stations provide additional convenience. Vacuum pump not included. Our policy of continuous development may cause the information and specifications contained herein to change without notice or liability. 5

7 Degassers FloVac Degasser Flow Degasser The FloVac provides cost effective vacuum degassing.
